Graph the function y = x + 3x2 - x - 3. Which lists all of the turning points of the graph rounded to the nearest
whole number?

(-3,0) and (1,0)
(-2,3) and (0, -3)
(-2,3), (-1,0), and (0, -3)
(-3,0), (-1,0), and (1,0)

I believe it's (-2,3), (-1,0), and (0,-3)

Step-by-step explanation:

y = x + 3x2 - x - 3 = y = 3x^2 - 3

I used desmos.com/calculator and mathpapa.com/algebra-calculator.html (I highly suggest using these sites. They tell you how to solve it step-by-step.)
